The main objective of the GPR data processing and interpretation is to select a velocity model for time-to-depth conversion. The modeling results allow to equate the distinguished layers with geological or glaciological objects. The paper describes an algorithm for calculating the diffraction traveltime curves realized within a model of dipping layer medium with an aim to construct appropriate velocity model. The efficiency of the described algorithm is illustrated by the GPR data collected during the austral summer field season of the 60th Russian Antarctic Expedition (2014/15) in the Mirny Station area, East Antarctica.
